Service Tips

Our heating and cooling staff are highly trained and qualified technicians in their fields.

With every service call they provide attention to detail, careful inspections, and knowledgeable answers to all of a customer’s questions.

A typical maintenance check-up should include the following:

  • Thermostat settings should be checked. To ensure the cooling and heating system keeps you comfortable when you are home and saves energy while you are away, adjustments can be made to better fit your schedule and save money in your wallet.
  • Tighten all electrical connections. Without connection of the electrical components, the system will not work properly if at all. The voltage and currents of the motors should be measured. Faulty electrical connections can cause unsafe operation of your system and reduce the life of major components.
  • Lubricate all moving parts. Parts that lack lubrication cause friction in motors and increase the amount of electricity you use. This leads to parts wearing down faster than they should. This in turn requires costly repairs. Not to mention, because the parts have to work harder to move they will use up more energy and electricity, causing utility bills to drastically increase.
  • Check the drains. Check and inspect the condensate drain in your central air conditioner, furnace and/or heat pump (when in cooling mode). A plugged drain can cause water damage and flooding in the house and affect indoor humidity levels causing mold and mildew.
  • Check the on and off switches. One should investigate controls of the system to ensure proper and safe operation. Check the starting cycle of the equipment to assure the system starts, operates, and shuts off properly.

Cooling Specific

  • Clean the Coils. Clean evaporator and condenser air conditioning coils. Dirty coils reduce the system’s ability to cool your home and cause the system to run longer, increasing energy costs and reducing the life of the equipment.
  • Check coolant/refrigerant. Check your central air conditioner’s refrigerant level and adjust if necessary. Too much or too little refrigerant will make your system less efficient increasing energy costs and reducing the life of the equipment.
  • Check the blower fan and motor. Clean and adjust blower components to provide proper system airflow for greater comfort levels. Airflow problems can reduce your system’s efficiency by up to 15 percent.

Heating Specific

  • Keep your eyes and nose open. Check all gas (or oil) connections, gas pressure, burner combustion and heat exchangers. Improperly operating gas (or oil) connections are a fire hazard and can contribute to health problems. A dirty burner or cracked heat exchanger causes improper burner operation. Either can cause the equipment to operate less safely and efficiently. Beyond visually inspecting, any odors coming from the system could be a sign of a leak or faulty connection.
  • Keep the heating source area clean. Any time a source of heat is present there is a danger of fire. To combat this danger, the area and floor surrounding the heating system and furnace should be kept free of clutter and debris. Be sure to sweep the floor when possible and dust, reducing the amount of particles sucked into the HVAC system.

Actions To Do Yourself

  • Inspect, clean, or change air filters once a month in your central air conditioner, furnace, and/or heat pump. Your contractor can show you how to do this. A dirty filter can increase energy costs and damage your equipment, leading to early failure.
